Uma i-powdery isikhutha ivela ku-petunia - indlela yokubhekana nalesi sihlava?

Send

I-Petunia ayisona isitshalo sangaphakathi kuphela, kodwa futhi isitshalo sangaphandle esisetshenziselwa ukuhlobisa imibhede yezimbali emazweni amaningi omhlaba.

Yize enganakekile ekunakekelweni, kwesinye isikhathi impushana enesikhunta iyamthinta. Kungenzeka yini ukuqeda lesi sifo?

Ngakho-ke, kule ndatshana uzofunda nge-powdery isikhutha, ukuthi isithinta kanjani imbali nokuthi ungalwa kanjani nayo ngempumelelo.

Kafushane ngesitshalo nezici zaso

Ama-petunias we-Cascading ne-ampelous akhula ngokushesha kunalawo ajwayelekile. Uma uxazulula le nkinga ngokukhanyisa okwengeziwe, ihlumela eliphakathi nendawo lizokwakhiwa masinyane, bese kuthi elilandelanayo, lisuke kulo nge-engeli elifanele. Ngokushoda kokukhanya, amahlumela ohlangothini akhula abe mabi kakhulu futhi akhule aye phezulu. Ungaguqula ukwakheka kwehlathi ngokushintsha izimo zokuboshwa.

Abalimi abanolwazi bancinza izihlahla ngesikhathi sokukhula. Benza lokhu ukunciphisa intuthuko ye-petunia. Abafuyi bakhulisa izinhlobo ezihlanganisiwe, bebeka kuzo isimo esihle sehlathi. Lapho uzikhulisa, akusetshenziswa izindlela ezikhethekile zezolimo. Zizodingeka ekukhiqizweni kwembewu yama-petunias ampelous: isihlahla sakhiwa ngokuncinza, kepha noma kunjalo ngeke sikwazi ukusiguqula sibe "yibhola" elibukeka kahle.

Okubalulekile. Ungayivimba kanjani i-ampelous petunias ekwakheni imivimbo emide? Kuyadingeka ukuvimbela ukuqhakaza kwazo kuze kube yilapho kwakhiwa isihlahla. Lokhu kuthatha izinyanga ezi-3 noma ngaphezulu.

Imininingwane eyisisekelo ngalesi sifo

I-Powdery isikhutha noma i-mycelium ye-parasitic powdery isikhutha i-parasite ehlasela amangqamuzana e-petunia futhi iphuze wonke ama-juice ayo. Uma ungakunaki ukuqhakaza okumhlophe, kungekudala amaqabunga aphansi azophenduka aphuzi, alenge futhi awe (kungani amaqabunga e-petunia ephenduka aphuzi?).

Kulezo zindawo lapho kufakwe khona ama-mycelium, kuvela izilonda... Izicubu eziphilayo ziyanyamalala njengoba izimuncagazi “ziyidla”. Isikhunta se-Powdery kunzima ukusibona: ukungabi bikho kwezakhamzimba akuthinti ama-petunias ngendlela engcono kakhulu. Ngenxa yokuphazamiseka enqubweni ye-photosynthesis, izofa uma kungathathwa izinyathelo eziphuthumayo zolawulo oluhlanganisiwe.

Izimbangela

Isikhunta se-Powdery yisifo sokukhunta esibangelwa ama-parasites ahlala ezingxenyeni ezingenhla zenhlabathi. Akuvamile ukutheleleka i-petunia uma umlimi eyinakekela. Uyazi ukuthi izinhlamvu ze-powdery isikhutha ziyasebenza ezimweni ezilandelayo:

Umoya opholile omanzi (amazinga okushisa emini nasebusuku azungeze u- + 20 degrees Celsius, futhi umswakama womoya wedlula ama-70%).
I-nitrogen eyeqile enhlabathini.
Ubuningi bezitshalo.
Ukunisela okungalungile nokungajwayelekile.

Kwesinye isikhathi i-powdery isikhutha sithinta i-petunia ngezinye izizathu. Ukutheleleka akwenzeki ngenxa yokungathobeli imibandela yokuboshwa. Isinambuzane sifika kuso kusuka ezitshalweni ezingomakhelwane, ngamanzi noma ngenxa yokungagcini izixwayiso zezimbali uqobo (ukuthena isitshalo esingeyona futhi esinempilo nethuluzi elifanayo ngaphandle kokwelashwa ngesisombululo sotshwala).

Ukuxilongwa

Ngokokuqala ngqá baqala ukukhuluma ngophawuda oluyimpuphu eRussian Federation ekuqaleni kwekhulu lama-20... Isisebenzeli sayo esiyimbangela yikhunta iSphaerotheca pannosa. Kulula ukubona isitshalo esinegciwane:

Okokuqala, kuvela ingubo emhlophe. Iyabonakala emaqabungeni nakuma-inflorescence.
Ezinsukwini ezimbalwa kamuva, amaconsi afana namazolo avela ezihlwini nasemacembeni.

Abalimi abanokuhlangenwe nakho bathi lesi sifo sisakazeka sisuka emaqabungeni aphansi siye ezingxenyeni ezingaphezulu, kufaka phakathi efihlekile. Ngaphandle kokuthatha isinyathelo, lesi sitshalo sizobola futhi sife.

Ukunakwa. Indlela enhle yokutshela ukuthi ngabe i-powdery isikhutha siyakhula ku-petunia ukubheka kahle emini.

Ungayisusa kanjani inkinga?

Ukwelapha i-petunia, izimo zokuboshwa ziyabuyekezwa:

Iyaniselwa kaningi futhi kungemva kokuba kubonwe ukuthi inhlabathi engaphezulu yomile.
Umlimi wezimbali uyeka ukuwufafaza, bese ebeka imbiza yezimbali efasiteleni, “elingcwatshwe” emisebeni yelanga.
Ikha amaqabunga aseduze komphetho wenhlabathi. Lesi senzo esilula sivimbela ukusakazeka kwesifo ezingxenyeni ezingenhla zesitshalo.

Akubona bonke abalimi abasebenzisa izidakamizwa ekulweni ne-powdery isikhutha, ngisho nokwazi ngokusebenza kwazo. Bakholelwa ekusebenziseni izindlela zabantu. UPetunia uzolulama uma elashwa ngesixazululo esilungiselelwe kusuka:

250 ml wobisi;
750 ml wamanzi;
1 tsp usawoti.

Ngemuva kokuxuba izithako ezingenhla, uthele ebhodleleni bese ufafaza i-petunia ngebhodlela lokufafaza.

Ukwelashwa kwe-algorithm ngomuthi we-fungicidal

Ukushintsha izimo zokugcina isitshalo. Isuswa ewindini eliminza emisebeni yelanga futhi inganiselwa kangako nge-petunia.
Izindawo ezinegciwane ziyasuswa, i.e. amaqabunga, amaqabunga aphuzi namacwecwe.
Isendlalelo esiphezulu senhlabathi siyasuswa, bese kuthi esikhundleni saso kuthululwe esinye - kusetshenzwe.
Futha ngama-fungicides, uwahlunge ngokwemiyalo yomkhiqizi.
Qiniseka ukuthi isixazululo singena kuzo zonke izingxenye ze-petunia.
Ezimweni ezinzima, isitshalo sifakwa esitsheni nesisombululo.

Amakhambi esintu asebenzayo

Isixazululo sensipho ngokufaka i-soda ash... Ukulungiselela, thatha ama-20-25 amagremu kasoda, amalitha ama-5 wamanzi ashisayo no-5 amagremu wensipho (yokuwasha ilondolo). Ingxube ipholile, bese ifafazwa ngayo empandeni yenhlabathi. Inqubo yokuphindaphinda izikhathi ezi-2 njalo ezinsukwini eziyi-7-10. Ungayifezi, ngoba izimpawu ze-powdery isikhutha sezinyamalele.
Isixazululo esibuthakathaka se-potassium permanganate... Ilungiswa ngokuqedwa kwamagremu ama-2-3 we-potassium permanganate kumalitha ayi-10-13 wamanzi. Imvamisa yokucubungula iba njalo ezinsukwini ezinhlanu. Inombolo yezinqubo yi-3.
Inhlanganisela yensipho nomlotha... Ilungiselelwe kusuka ku-1 kg womlotha wokhuni namalitha ayi-10 wamanzi ashisayo. Ngemuva kokuvusa nokugcizelela izinsuku ezingama-5-7, engeza enye u-5-10 amagremu wensipho kuyo bese ucubungula isihlahla. Ngaphambi kwalokho, kuhlunge. Umlotha awulahlwa bese uthelwa ebhodweni lokudla.

Umkhandlu. Amakhambi esintu achazwe ngenhla ngeke asize uma umlimi eqaphela i-powdery isikhutha kuma-petunias sekwephuzile.

Yikuphi kwe- "chemistry" okungcono ukucubungula?

Ama-fungicides asiza ukulwa ne-powdery isikhutha. Zonakalisa isakhiwo sefungus, zivimbela ukukhula kwazo kumaseli ezimbali.

Fundazol

Le fungicide ibanzi. Kuyasiza uma kutholakala izifo zamaqabunga, ezeziqu kanye nembewu ezitshalweni zasendlini. Ukusebenza kwe-Fundazole kungenxa yokuba khona kwe-benomyl ekwakhiweni.

Le nto ingena kulesi sitshalo ngamaqabunga nezimpande. Ngemuva kwalokho, iguqulelwa ku-carbendazim, ekhombisa izindawo ezinhle kakhulu ze-fungicide. Ngemuva kokucubungula, i-Fundazol ihlala phezulu. Ingena kuphela kulesi sitshalo. Ngenxa yalokhu, i-petunia ivikelwe kangcono ekuthelelekeni kabusha nge-powdery isikhutha.

I-Fundazole ithengiswa ngo-10 gram sachet. Intengo - ama-ruble ayi-17. Indlela yokuhlanza - 1 gram / 1 tsp. amanzi. Ngemuva kokuqedwa kokuqala, umthamo wesisombululo esisebenzayo uletha ku-1 litre... Kungcono ukuhlanganisa ukuchelela nokufafaza ukususa ukhunta. Phakathi nenkathi, lesi sitshalo siphathwa kabili, uma bekungekona okokuqala ukusibhubhisa.

I-Amistar eyengeziwe

Le fungicide ehlanganisiwe iyasebenza ukulwa nezifo eziningi, kufaka phakathi i-powdery isikhutha. Ngosizo lwakhe:

yandisa isikhathi sokukhula;
ukwandisa ukusebenza kahle kwamanzi;
sithuthukise isithombe, ukushintshaniswa kwe-nitrogen;
vimbela ukwakheka kwe-ethylene.

I-Amistar extra iyisidakamizwa esikhiqizwa ngendlela yesisombululo esinamandla. ERussia, bayayithengisa ngamathini elitha ngentengo yama-ruble ayi-1,500 / ilitha elilodwa. Isixazululo esisebenzayo silungiswa ngokuxuba i-fungicide namanzi endaweni ehlushwa ngo-1: 10 noma ngo-1: 4. Ngemuva kokunyakaza, isitshalo siphathwa ngaso.

Ijubane

Ungayelapha i-petunia uma uthenga i-Skor yokuxhumana ne-systemic ngentengo yama-ruble angu-8300 nge-1 litre. Isithako esikhulu esisebenzayo kuwo yi-difenoconazole.

Ukuze uthole ukwelashwa, thenga 2 ml womuthi kumalitha ayi-10 amanzi. Ayisetshenziselwa ukucubungula ngokushesha ngemuva kokuxubeka. Ezinsukwini ezingamashumi amabili kamuva, i-petunia ilashwa kathathu.

Isithombe

Esithombeni osinikezwe ngezansi, ungabona ukuthi i-petunia ethinteka kanjani yi-powdery isikhutha ibukeka kanjani nokuthi ungabhekana kanjani nalesi sifo ekhaya:

Izindlela zokuvimbela
